Crickets and other useful tools.
Did you know that to figure the outdoor temperature in Faheinheit... you simply count the number of chirps a cricket makes in 15 seconds.... and add 37? I remembered this this morning as I left the house and heard a cricket chirping..
So I was wondering what other useful ways of using the world around us do people have to predict or determine things. I guess I'm talking about Old Wive's Tales.. What stuff do YOU know..
